We're sorry this happened. Here's what to do.
Contact support right away, from another phone or device. We can lock your account and unlink the lost phone.
When you have a new phone, sign in with your phone number, an SMS code and your passcode.
Why the rush? Nobody can send crypto from your account without your ArtPay passcode. But someone who knows your phone's screen lock could see your card details. So the sooner you tell us, the better.
